Vehicle Component Addressing via Segmented IPv6 Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods do not provide a uniform addressing solution for vehicle components that can be used both inside and outside the vehicle, leading to inefficiencies in component identification and access.
Innovation Solution
A method for determining a unique IPv6 address for vehicle components by storing a vehicle identification in a network field and a component identification in a host field, allowing for unambiguous addressing regardless of the component's location within the vehicle, using a communication unit to transmit and store the vehicle identification, and updating addresses as needed for replaced components.

Engineering Contradiction Analysis
1Adaptability or versatility
If existing addressing methods are used for vehicle components, then component identification inside the vehicle is possible, but uniform addressing both inside and outside the vehicle is not achieved
Solution Approach 1:
The patent applies universality by creating an IPv6 address structure that serves dual purposes: internally within the vehicle network and externally when the vehicle connects to external networks. The address format combines vehicle identification (VIN) and component identification in a standardized IPv6 structure, allowing the same address to function both inside the vehicle and on external networks, eliminating the need for separate addressing schemes.
Solution Approach 2:
The patent segments the IPv6 address into distinct fields: the first field contains vehicle identification information (such as VIN), and the second field contains component identification information. This segmentation allows each part of the address to serve its specific function while together they provide a complete, unique identifier that works both internally and externally.
2Extent of automation
If manual addressing methods are used for vehicle components, then addressing flexibility is possible, but automation and efficiency are reduced
Solution Approach 1:
The patent implements self-service by enabling components to automatically determine their own IPv6 addresses using the standardized format. When a component joins the network, it can autonomously construct its address by combining the vehicle identification (obtained from the vehicle's network or broadcast) with its own component identification, eliminating the need for manual address assignment while maintaining flexibility through the structured format.
Solution Approach 2:
The patent applies preliminary action by pre-defining the address structure format that combines vehicle identification and component identification fields. This predefined structure is established before actual address assignment occurs, allowing automated systems to efficiently generate valid addresses by simply filling in the appropriate identification values according to the predetermined format.

AI summary
A method is provided for determining an address of a component of a vehicle, wherein a vehicle identification is determined and stored in a first field of the address, and wherein an identification of the component is stored in a second field of the address. Furthermore, a method for accessing a component of a vehicle, in particular, a control unit of the vehicle, by use of the determined address of the component is provided, as well as a vehicle with at least one such component is also proposed.
